Self-adaptive neodymium iron boron coating binding force drop test device

The utility model relates to the technical field of neodymium iron boron coating binding force test equipment, in particular to a self-adaptive neodymium iron boron coating binding force drop test device. Comprising a falling box for collecting experimental sample blocks and limiting frames oppositely arranged on the two sides of the falling box, and further comprises a driving unit for driving lifting; the sliding frame is in sliding fit between the limiting frames, and limiting blocks for limiting sliding of the sliding frame are arranged at the tops of the limiting frames; the separation disc is fixed to the lower side of the sliding frame through the extension frame, and the adsorption disc is in sliding fit with the lower side of the sliding frame and makes contact with the upper surface of the separation disc; in the process that the driving unit drives the sliding frame to ascend, the limiting block limits sliding of the sliding frame, so that the magnetic suction cup moves upwards to be separated from
